3. The sampling distribution will be approximately normal when the sample size is sufficiently large.

4. The mean of the sampling distribution will be equal to the population mean.

Answer #1

The Central Limit Theorem says that when sample size n is taken
from any population with mean μ and standard deviation σ when n is
large, which of the following statements are true?

Question Central Limit Theorem
a)According to the Central Limit Theorem, what
are the mean and standard deviation of the sampling distribution of
sample means?
b)A population has a mean ?=1800 and a standard
deviation ?=40. Find the mean and standard deviation of the
sampling distribution of sample means when the sample size
n=100.

What is wrong with the following statement of the central limit
theorem?
Central Limit Theorem. If the random variables X1,
X2, X3, …, Xn are a random sample of size n from any distribution
with finite mean μ and variance σ2, then the distribution of will
be approximately normal, with a standard deviation of σ / √n.

Which of the following is NOT a conclusion of the Central Limit
Theorem? Choose the correct answer below.
A. The distribution of the sample means x overbar will, as the
sample size increases, approach a normal distribution.
B. The mean of all sample means is the population mean mu.
C. The distribution of the sample data will approach a normal
distribution as the sample size increases.
D. The standard deviation of all sample means is the population
standard deviation divided...

The Central Limit Theorem implies that [Select the correct
answers - There may be more than one correct answer. Negative
marking will apply for incorrect selections.]
(a) All variables have bell-shaped sample data distributions
if a random sample con- tains at least about 30 observations.
(b) Population distributions are normal whenever the
population size is large.
(c) For large random samples, the sampling distribution of y ̄
is approximately normal, regardless of the shape of the population
distribution.
(d) The...

The Central Limit Theorem indicates that in selecting random
samples from a population, the sampling distribution of the the
sample mean x-bar can be approximated by a normal distribution as
the sample size becomes large.

Given a population with mean μ=100 and variance
σ2=81, the Central Limit Theorem applies
when the sample size n≥30. A random sample of size
n=30 is obtained.
What are the mean, the variance, and the standard deviation of
the sampling distribution for the sample mean?
Describe the probability distribution of the sample mean and
draw the graph of this probability distribution with its mean and
standard deviation.
What is the probability that x<101.5?
What is the probability that x>102?

The Central Limit Theorem allows us to make predictions about
where a sample mean will fall in a distribution of sample means.
One way it does this is by explaining (using a formula) how the
shape of the distribution will change depending on the sample size.
What part of the Central Limit Theorem tells us about the shape of
the distribution?
The part that explains that there is no standardized table you
can use to find probabilities once you use...

C. none of these
D. states that the mean of the sampling distribution of the
